How is current measured in a circuit?

Current in a circuit is measured in Amperes, often abbreviated as "A." Amperes quantify the flow of electric charge through a conductor, representing how many charges pass a given point per unit of time. This is essential for understanding how much electricity is flowing in a circuit, which is crucial for various calculations and applications in electrical engineering and electronics.

The other units mentioned have different applications: Volts measure voltage or electric potential, Ohms measure resistance within a circuit, and Watts measure the power consumed or produced in the circuit, which is the product of voltage and current. Understanding these distinctions is vital for anyone working with electrical systems, as each unit serves a specific role in analyzing and designing circuits.
